The following measure 1) or 2) shall

be implemented.

1) VDD or VDDQ18 shall be turned

on after the corresponding pin

voltage, IOV is turned on. The

combinations of power-on

sequence are as follows;

IOV → VDD → VDDQ18

IOV → VDDQ18 → VDD

VDD → IOV → VDDQ18

VDDQ18 → IOV → VDD

2) External pullup resistor shall be

less than or equal to 2.7 KΩ.
